Waiting in long queue is undesirable due to which in some practical situations customers become impatient and leave the system. In such cases providing additional servers can reduce long queue. This investigation deals with multi-server queueing system with additional servers and discouragement. The customers arrive in poisson fashion and are served exponentially by a pool of permanent and addi...

Treatment of chicken blood smears and semithin sections from Epon-embedded mouse tissues with aqueous solutions of the 3-aminonaphthalimides FA-142, FA-2043, and FA-2143 induced a strong green-yellow fluorescence of chromatin under violet or violet-blue excitation. Chromatin emission was abolished by previous DNase or hot TCA treatment. The use of 3-methoxy (FA-655) and 3-nitro derivatives (M-4...

The problem of climate change is one the most crucial issues today. various impacts that have occurred due to increased world community's awareness effects in future. This was exacerbated by existence U.S. foreign policy when Trump administration voted exit Paris Agreement. lack research into impact U.S withdrawal from Agreement on tackling global has prompted study. paper will analyze what ari...

We consider the problem of tiling a segment {0, . . . , n} of the discrete line. More precisely, we ought to characterize the structure of the patterns that tile a segment and their number. A pattern is a subset of N. A tiling pattern or tile for {0, . . . , n} is a subset A ∈ P(N) such that there exists B ∈ P(N) and such that the direct sum of A and B equals {0, . . . , n}. This problem is rel...

Is globalization conducive to long-run economic growth and development? Almost certainly yes. But as for trade’s impact on long-run political growth and development, here the state of our knowledge lags far behind. This chapter attempts to redress the imbalance. Rather than focus on globalization’s longer-run economic externalities, I highlight the political consequences of openness—e.g., the d...

Multirings are objects like rings but with multi-valued addition. They are a variant of other objects called hyperrings, defined by Krasner [12], [13]. In [16] the second author defines multirings, introduces a certain special class of multirings called real reduced multirings, defines a natural reflection A Ã Qred(A) from the category of multirings satisfying −1 / ∈ ∑ A2 to the full subcategor...

The main purpose of this paper is to introduce the compatibility of $M$-fuzzifying topologies and $M$-fuzzifying convexities, define an $M$-fuzzifying topological convex space, and give a method to generate an $M$-fuzzifying topological convex space. Some characterizations of $M$-fuzzifying topological convex spaces are presented. Finally, the notion of $M$-fuzzifying weak topologies is obtaine...
